RAINCLAD

Thermawool Rainclad® is a non-combustible stone wool insulation board designed for use within ventilated rainscreen façade systems. Manufactured from volcanic basalt rock, Rainclad provides reliable thermal insulation, fire resistance and acoustic absorption within external wall constructions.

The product incorporates a factory-applied hydrophobic treatment to reduce water absorption during installation while maintaining vapour permeability within the wall build-up. With a nominal density of 60 kg/m³ and a declared thermal conductivity of λ = 0.035 W/mK, Rainclad delivers high-performance thermal insulation suitable for modern façade systems.

Rainclad insulation is suitable for buildings of any height, including those exceeding 18 metres, when used within compliant non-combustible façade constructions.
